learn how to read a compressor map. How retarded is the spool up??

props for turbo D.

 

D15 with a huge turbo like that is going to surge sometimes. The engine doesnt need nearly the airflow that the HX-40 wants to push and air backs up and slows the compressor wheel. Nothing you can do about it since you already have an anti-surge housing.

 

4000 rpm in what gear? 5th? lol

 

first off props for doing it. second, it's gonna blow up. You know what CFM that thing is putting out at 10psi??? fuking a. And running it on the blue box? wtf
but anyways thanks for doing it and goodluck

 

please put a ziptie around the rubber hose on your wastegate

 

Looks likea decent sized turbo. I have one laying around, maybe I will rock the holset.

 

10 psi. no managment. good luck

 

that is INSANE!!!!!!

U ARE THE MAN! lol!

 

I'll tell you avery good possible cause, too much backpressure on exhaust side, you have a cast collectorless manifold...

Your downpipe looks really small too but it looks like your A.C. compressor is in the way.

 

big turbos are over-rated.

 

yeah mang! props for doin it but im pretty sure that turbo shouldnt be run at UNDER 10psi, which is probably where the surge is coming from, also did you make that .48 housing fit the exhaust side????, looks like someone ported it to fit the bigger holset wheel

 

madd props. just one question: did you get the housing ported locally or through an h-t vendor or someone else online? gl. ill be doing a h1c with a .61 a/r housing.
